Is a nucleotide a phosphate sugar nitrogen base?

In a nucleotide the 5-carbon sugar is bonded to the phosphate group, which is bonded to the nitrogenous base. In a chain of nucleotides (a strand of DNA), the nucleotides are connected by covalent bonds between the sugar of one nucleotide, and the phosphate group of the next nucleotide.

What makes up the ladder of DNA molecules?

The DNA molecule consists of paired nucleotides that make each "rung" of the ladder. Each nucleotide is made up of a one of four nitrogenous bases (adenine, guanine, cytosine, or thymine), a five-carbon sugar (either ribose or 2'-deoxyribose), and a phosphate molecule.
